standing waves on a guitar string

Standing waves on a guitar string form when waves traveling down the string reflect off a point where the string is tied down or pressed against the fingerboard.The entire series of distortions may be superimposed on a single figure, like this (Intro 2 figure) , indicating different moments in time using traces ofdifferent colors or line styles.

What is the wavelength λ of the standing wave shown onthe guitar string?

Expert Solution

We know the distance between two successive nodes = λ / 2

From figure distance between two successive nodes = 20 cm

i.e. λ / 2 = 20 cm

so, the wavelength of the standing wave λ = 40cm

A guitar is an excellent example of standing waves on strings. If you tighten a guitar string, what effect will it have on the frequency of the note it produces when strummed? Explain in terms of our formula, f2= FTensionμλ2 When a guitar player uses their finger to pin down the string somewhere on the neck of the guitar, the frequency of the note the string produces also changes. Explain why this change might occur, in terms of our formula,...

n the Group Work, we examine standing waves on a string. In order to calculate the velocity of the wave, what two properties do we need to know? The INERTIAL and ELASTIC properties of the wave medium. For a string, these are the DENSITY and the YOUNG'S MODULUS of the string. The INERTIAL and ELASTIC properties of the wave medium. For a string, these are the MASS/LENGTH and the TENSION of the string. The INERTIAL and ELASTIC properties of the...

Vibration from a 620 Hz tuning fork sets up standing waves on a string clamped at both ends (one of which you may take as x=0). The travelling wave speed on this string is 440 m/s. The standing wave has four anti-nodes and an amplitude of 2.0 mm. (a) What is the length of the string? ___ m (b) Write an equation for the transverse displacement of the string as a function of position and time: y(x,t) = ( ___...

problem 1. You notice that a string fixed at both ends produces standing waves at 440 Hz and 660 Hz, but not at any frequency in between. a.What harmonics do these two frequencies correspond to? b. What is the fundamental frequency? problem 2. A bass clarinet can be modeled as a 120-cm-long tube closed at one end. A musician starts playing at room temperature (vsound = 343 m/s), but the temperature soon increases to where the speed of sound is...

The physics of wind instruments is based on the concept of standing waves.

The physics of wind instruments is based on the concept of standing waves. When the player blows into the mouthpiece, the column of air inside the instrument vibrates, and standing waves are produced. Although the acoustics of wind instruments is complicated, a simple description in terms of open and closed tubes can help in understanding the physical phenomena related to these instruments. For example, a flute can be described as an open-open pipe because a flutist covers the mouthpiece of...
